Hey All,

I am looking to introduce 2 tasks into MonkeyLogic

1. Rapid Serial Presentation - Essentially having a bunch of images, 200 msec on, 200 msec off. Can the ITI be that low? is there a way to buffer images or structure the task where this is possible?

2. Receptive Field mapping - the same as the first task, but with the ability to vary the location of the Taskobject randomly. What is the best approach for that?

You can present a bunch of images in one scene. I don't have time to explain now and I don't know how many images you have, but take a look at 'task\runtime v2\12 LBC fMRI task'. It is written for your kind of task.

Thanks for the tip. I tried running this example and got the error below:

"

<<< MonkeyLogic >>> Input must be a row vector of characters or string scalar. (fileparts, Line 34)
Error using fileparts (line 34)

Error in mglimread (line 3)
[~,~,e] = fileparts(filename);

I don't know what happened. You may just need to try the latest package. The new package also has a userloop version of the task, which lets you re-use pre-created stimuli and save memory.

This happened with the May 21st Build, I'll update to the one you just released.
